Be it knownthat I, GEORGE SEYMOUR, of No..54 Lime street, iii the city of London, England,a sub-k Vject of the Queen ot Great Britain, have invented or .discovered new and useful Improvements in the construction ofShips-andVessels 4to, facilitate the steer ing and `propelling the same; and I, the said GEORGE SEYMOUR, do hereby declare the nature of the said invention, and in what marinier the same is' to be per formed, to be particularlydescribed and-ascertained in and by the following `stat-ement thereof; that is to In constructing ships or `vessels according to my invention, I extend'the stern-postsomewhatfurther aft than now usual, and on `each side of the sternfpost at `its fore part,- 1` hang a rudder, which can be back `against the stern-post-,and can also be moved out to an angle, to st eerthe ship; Through the stern-post,

`and. `between the two "rudders, I carry a propellers hal't, which at its end, has a screw propellerupon it; by this arrangement I` am `enabled to Lplace the screw propeller further aft thanwas practicable with the screw before `the rudder.' 'v

When the lscrew propeller is used as auauxiliary propeller, Iprefer that it should be formed with two blades,'an`d 1 then formjthe stern-post of somewhat greater width than usual, sothat, when the propeller is out of use, it `may lbe-setwith its/,blades in a vertical position, s0 that the propeller-blades may be behind the stcrn-postand not project beyond or to any great extent beyond it. The two rudders may actinl dep 4ndently one 'of the other and be worked `by sepa `rate steering-wheels.

And, in'order tha-t my said invention may be most fully `understood and readily carried into effect, I will proceed to describe the drawing hereunto annexed.

Description of the Drawing.

Figure 1 is a side 'view of the stern of an iron ship, constructedaccording to my invention,'with a double rudder in front of the. propeller, and hung 'on either side of an extendedjstern-post.

Figure 2 is an end view ofthe same a a isa deep but thin stern-post with the propellerpipe b passing through it. l

e is the propeller; and

dd .the double-rudder, the two `tiaps` or parts of which are `capable of folding close in against the sternpost, they being suitably hollowed for the recept-ion of the. propeller-pipe.

Figure 3 shows a side View, and 4. Figure 4 in end View, a modification of the arrange- `ment applicable especially to wooden or composite i ships with auxiliary power, or iron ships ,with boxl or theiraxes, on which the steering-ropes h are wound and unwound alternately. There are lfour of the ropes h, one on either. side of' each tiller; it is made fast to the tiller at one end, then it passes around a fixed pulley to asheave on the head of the tiller, from wlence it returns around another fixed pulley to one of the barlels g., on which it is wound and to which its end is fixed. j

The drawing represents the ltillers as they stand, when both the rudder-ilaps are lying close against the stern-post; by turning one of steering-wheels the cor-k responding rudder-flap will be acted on, its tiller being drawn over-.by the-winding up of one of the" ropes h on its barrel g, whilst the other is unwound; or the two tillers may be worked by screw-gear of any ordinary construction, each tiller having its own ear. g Another arrangement is shown, in plan, in yFigure 6, by mea-ns of which lche two rudder-flaps may be worked by one steering-wheel.

k k are the heads of the main pieces of the rudders, each provided with two arms, l and m.

The rudder-heads are received into slots in the sliding frame n, which is'carried in fixed guides, and is :capable of being. traversed by the screw o and steering-wheel jp.

The arms l are above the level of the frame a, but, as the frame travels, they are. acted on by projections n 'n' rising from the upper surface of the frame. p

Similarly, the arms m are below the level of the frame n and are acted on by projections, a?, beneath it.V v

Vessels propelled by twin screws, paddle-wheels, hydraulic mechanism, or sails, may be similarly constructed.

"The combination of the double rudder andl sternpost, substantially as described.

Also, the combination of thevdouble rudder, stern-` post, and screw propeller, substantially' as described.
